winform 菜单激发窗体切换做法

经常会用到类似于下图这样的winform窗体，其中点击各个菜单时于鏊做到内容窗体的切换，今天也记录一直切换的方法

在主窗体放置一个panal，所有的内容窗体均在改panal上呈现，实现以下方法

///实例化主窗体

private void FrmSetup_Load(object sender, EventArgs e)
        {
            this.btnSystem_Click(null, null);
        }

///初始化内容窗体

public FrmSetup(uint uiDeviceSN)
            : this()
        {
            m_uiDeviceSN = uiDeviceSN;
            m_devSetupRefObj = new DevSetupRefObj(m_uiDeviceSN);
            string sIniPath = this.m_uiDeviceSN.ToString("D08") + "\\Setup\\Setup.ini";
            if (File.Exists(sIniPath))
            {
                m_devSetupRefObj.LoadLocalSetup(sIniPath);
            }
            else
            {
                m_devSetupRefObj.LoadDeviceSetup();
            }

m_frmBaseSysSetup = new FrmBaseSystemSetup(m_uiDeviceSN, m_devSetupRefObj);
            m_frmEditSetup = new FrmEditSetup(m_uiDeviceSN, m_devSetupRefObj);
            m_frmPrintSetup = new FrmPrintSetup(m_uiDeviceSN, m_devSetupRefObj);
            m_frmUserSetup = new FrmUserSetup(m_uiDeviceSN, m_devSetupRefObj);
            m_frmMoreSetup = new FrmMoreSetup(m_uiDeviceSN, m_devSetupRefObj);
            m_frmRegister = new FrmRegister(m_uiDeviceSN, m_devSetupRefObj);
        }
///实例化内容窗体
        FrmBaseSystemSetup m_frmBaseSysSetup;
        FrmEditSetup m_frmEditSetup;
        FrmPrintSetup m_frmPrintSetup;
        FrmUserSetup m_frmUserSetup;
        FrmMoreSetup m_frmMoreSetup;
        FrmRegister m_frmRegister;

private void btnSystem_Click(object sender, EventArgs e)
        {
            this.ShowSystem();
            this.HideEdit();
            this.HidePrint();
            this.HideUser();
            this.HideMore();
            this.HideRegister();
        }

///窗体切换

private void ShowUser()
        {
            pnlShow.Controls.Clear();

m_frmUserSetup.TopLevel = false;
            m_frmUserSetup.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
            pnlShow.Controls.Add(m_frmUserSetup);

this.m_frmUserSetup.ShowForm();  
        }

以上就是大致思路。
